What is the significance of the term halakha lmaase? הלכה למעשה

By chavurah on December 27, 2019

Explain what halakha lmaase means, maybe examples of how it is applied? l’maase= for doing? “common practice”?

I heard the term in a shiur about responsa centering around the question ‘What liquids are permitted for havdalah (besides wine) Is orange juice permissible?”? Is this a halakha lmaase because using orange juice for havdalah is a “common practice” (it isn’t though?).
